Title: Surge current-limiting circuit for a large-capacitance load
Inventor: MCCAFFERTY LORY N
IPC: H03K17/082
Filed: 1991-07-02
Abstract: A circuit for limiting switch-on surge current to a load including a large capacitance (12) includes a MOSFET (14) whose controlled path is connected in series with the capacitance across power supply terminals (+,-). A resistor (16) and a capacitor (20), having a relatively small capacitance, are connected in series with the controlled path, and a junction between the resistor and capacitor is connected to a gate of the MOSFET via a resistor (18) to provide a negative feedback path for charging the load capacitance with a constant current when power is applied. A capacitor (22) prevents initial turn-on of the MOSFET, and a zener diode (24) limits the gate voltage. Another arrangement uses a differential amplifier (50). The resistive part (10) of the load can be connected in parallel with the load capacitance, or to the power supply terminals for which it can be switched depending upon the gate voltage.

Patent CA-2089221-A1 (CA)
Inventor: KHAYAT RENE E
IPC: A43C15/14
Filed: 1993-02-10
Abstract: Disclosed is a retractable spike assembly insertable into a cavity made for this purpose in the bottom surface of a footwear heel or sole, the assembly comprising spikes that can be extended whenever needed, such as on icy roads, rock or wet grass and to be pulled in when they are not wanted, such as inside ahouse. The spikes are mounted on a carrier plate extending parallel to a bottom plate extending flush with the bottom surface of the heel or sole when the assembly is mounted in the cavity. A guide pin rigidly connected to the bottom plate in the middle of the same is used to guide the carrier plate up and down. The upwards movement of the carrier plate is achieved  with a compression spring mounted onto of the guide pin, the downwards movement being achieved with a cam held above the carrier plate. The cam is advantageously operated with a coin or any similar item thanks to a cylindrical peg inserted into a cylindrical through hole provided in a side wall of the cavity, the peg being held in the through hole by a locking pin. This retractable spike assembly is much simpler in structure and installation than the existing ones.

Patent CA-2095629-A1 (CA)
Title: Multi-chamber vial
Inventor: HABER TERRY M
IPC: A61M5/24
Filed: 1991-10-18
Abstract: A vial (2) has first and second chambers (56, 54) initially separated by a rupturable barrier (20). The first chamber (56) is a variable volume chamber defined by a cylinder (18), the rupturable barrier (20) at the second end (19) of the cylinder (18) and a piston (14). The second chamber (54) is created by a telescoping container (22) mounted to a second end (19) of the cylinder (18).  The chambers (56, 54) are telescopically collapsed causing fluid pressure in the second chamber (54) to rupture the barrier so the components mix in the first chamber (56). The piston (14) is driven through the cylinder (18) from pre-mix to post-mix positions by the liquid from the second chamber (54). This dislodges a safety shield (30) at the first end (17) of the cylinder (18) to expose the piston (14). The mixed contents of the first, variable volume chamber (56) are removed by inserting a needle cannula (18) through the now exposed piston (14); aspiration of the mixed contents take place without the introduction of air into the first chamber (56) since the piston (14) moves back down the cylinder (18) as the contents are removed. A spike adapter (120) can be used to transfer the contents of the vial (2) to a conventional IV bag (146).

Patent CA-2107459-A1 (CA)
Inventor: DANIEL STEVEN A
IPC: A61B18/04
Filed: 1992-04-03
Abstract: An instrument for cutting, ablating; and coagulating tissue has a rod (4) of ferromagnetic material fusion welded to the base of a conical tip (2) of copper with the rod adjacent the base of the conic being of lesser diameter than the base to provide a region to accept a potted coil (8) of wire about the rod whereby when the coil is connected to a constant current high frequency source the rod and tip are heated to a temperature approaching the Curie temperature of the ferromagnetic rod. As Curie temperature is approached the rod becomes essentially non-magnetic, heating decreases to produce a temperature below Curie temperature and the cycle repeats.  As a result of the excellent heat exchange interfaces produced by fusion welding the energy delivered to the tissue or other load which may be non-biological is closely controlled by temperature which is self regulated. A ferromagnetic sleeve is placed about the coil to concentrate magnetic flux in the rod. An outer sleeve spaced radially from the ferromagnetic sleeve and of relatively non-heat conductive material extends from the base of the tip away from the tip to provide a handle for the instrument.
